The analog part is realized differentially – this means, the differential bridge sensor signal is internally handled via two signal lines, which are rejected symmetrically around an internal common mode potential (analog ground = VDDA/2). Consequently, it is possible to amplify positive and negative input signals, which are located within the common mode range of the signal input. Figure 2.1 Block Diagram of the ZSC31150 The differential signal from the bridge sensor is pre-amplified by the Programmable Gain Amplifier (PGA). The Multiplexer (MUX) transmits the signals from either the bridge sensor, the external diode, or the separate temperature sensor, to the Analog-to-Digital Converter (ADC) in a certain sequence (instead of the temperature diode, the internal pn-junction (TS) can be used optionally). Afterwards, the ADC converts these signals into digital values. The digital signal correction takes place in the calibration microcontroller (CMC). It is based on a correction formula located in the ROM and on sensor-specific coefficients stored in the EEPROM during calibration. Dependent on the programmed output configuration, the corrected sensor signal is output as an analog value or in a digital format (I²C TM or ZACwireTM). The configuration data and the correction parameters can be programmed into the EEPROM via the digital interfaces.
